Description

중앙 구동방식의 농업용 작업기Agricultural work machine of central drive type
본 발명은 중앙 구동방식의 농업용 작업기에 관한 것으로서, 보다 상세하게는 농용 트랙터의 동력을 전달받아 작업기를 구동시키기 위한 기어박스를 작업기의 중앙부에 구성한 중앙 구동방식의 농업용 작업기에 관한 것이다.The present invention relates to a centrally driven agricultural working machine, and more particularly, to a centrally driven agricultural working machine in which a gearbox for driving the working machine by receiving power from an agricultural tractor is configured in the central part of the working machine.
일반적으로, 농업용 작업기 중 하나인 로터베이터(Rotavator)는 작물의 파종이나 이식을 하기 위하여 땅을 경운하는데 사용되는 농기계이다.In general, a Rotavator, one of agricultural working machines, is an agricultural machine used for cultivating land for sowing or transplanting crops.
즉, 로터베이터는 농업용 작업 차량인 농용 트랙터에 장착되어 트랙터의 엔진으로부터 동력을 전달받는 칼축에 구비된 다수의 경운날이 회전되면서 농지를 적정 깊이로 경운하여 작물의 파종 또는 이식을 할 수 있도록 한 것이다.That is, the rotavator is mounted on a farm tractor, which is an agricultural work vehicle, so that a plurality of tillage blades provided on a knife shaft receiving power from the engine of the tractor are rotated to plow the farmland to an appropriate depth so that crops can be sowed or transplanted. will be.
이러한 로터베이터는 대한민국 등록실용신안 제20-0492282호(이하 '선행기술문헌'이라 한다)에서 제안된 바 있다.Such a rotavator has been proposed in Republic of Korea Utility Model Registration No. 20-0492282 (hereinafter referred to as 'prior art literature').
선행기술문헌에 개시된 종래의 로터베이터는, 트랙터의 동력이 전달되는 동력전달부가 상부 중앙 영역에 구비되고, 양단부가 각각의 측판으로 마감된 본체와, 동력전달부와 양 측판 사이에 각각 설치된 양측의 지지프레임과, 동력전달부에 일측단이 연결된 상태로 타측단이 일측 지지프레임 즉 좌측 지지프레임을 통해 좌측의 측판을 관통하여 회전 가능하게 구비되는 기어결합축과, 기어결합축의 좌측단에 결합 고정된 상태로 회전되는 제1 스프로킷휠과 체인으로 연결되는 한편 칼축에 결합 고정된 상태로 회전되는 제2 스프로킷휠로 이루어진 기어박스가 구성된다.The conventional rotavator disclosed in the prior art literature has a main body in which the power transmission unit to which the power of the tractor is transmitted is provided in the upper center area, and both ends are finished with respective side plates, and both sides installed between the power transmission unit and both side plates, respectively. With one end connected to the support frame and the power transmission unit, the other end passes through the left side plate through one support frame, that is, the left support frame, and the gear coupling shaft provided rotatably and coupled to the left end of the gear coupling shaft. A gearbox is composed of a first sprocket wheel rotated while connected by a chain and a second sprocket wheel rotated while being coupled and fixed to the knife shaft.
이때, 칼축에는 다수의 경운날이 결합 고정된 상태로 설치되어 칼축에 의해 회전되면서 농지를 적정 깊이로 경운하게 된다.At this time, a plurality of tillage blades are installed in a coupled and fixed state on the shear shaft, so as to be rotated by the shear shaft, the farmland is plowed to an appropriate depth.
즉, 트랙터의 동력이 동력전달부로 전달되어 오면, 이의 동력은 동력전달부에 연결된 기어결합축으로 전달되어 기어결합축을 지지프레임 내에서 회전시키게 되고, 기어결합축에 결합 고정된 제1 스프로킷휠이 기어결합축과 같이 회전됨에 따라 체인으로 연결된 제2 스프로킷휠이 회전되며, 제2 스프로킷휠의 회전에 의해 칼축이 회전되면서 다수의 경운날이 농지를 경운하게 된다.That is, when the power of the tractor is transmitted to the power transmission unit, the power is transmitted to the gear coupling shaft connected to the power transmission unit to rotate the gear coupling shaft in the support frame, and the first sprocket wheel coupled and fixed to the gear coupling shaft As the gear coupling shaft rotates, the second sprocket wheel connected by the chain rotates, and as the knife shaft rotates by the rotation of the second sprocket wheel, a plurality of tillage blades plow the farmland.
하지만, 종래의 로터베이터에서는 트랙터의 동력을 칼축까지 전달하기 위한 동력전달수단 즉 기어박스가 로터베이터의 좌측에만 구성돼 있기 때문에, 로터베이터는 우측보다 기어박스가 있는 좌측이 상대적으로 더 무겁게 형성되므로 이러한 무게의 불균형으로 인해 로터베이터가 좌측으로 기울어져 수평 즉 평형 유지가 어려운 단점이 있다.However, in the conventional rotavator, since the power transmission means for transmitting the power of the tractor to the knife shaft, that is, the gearbox, is configured only on the left side of the rotavator, the left side with the gearbox is relatively heavier than the right side of the rotavator. Due to this imbalance of weight, the rotavator tilts to the left, which makes it difficult to maintain a horizontal, i.e. equilibrium, disadvantage.
이와 같이 로터베이터의 평형 유지가 안되면, 경운날이 기울어진 상태로 농지를 경운하게 되므로 농지의 경운 깊이가 달라져 농지를 고르게 경운할 수 없는 이차적인 단점이 있다.In this way, if the equilibrium of the rotavator is not maintained, since the farmland is plowed with the tiller blade tilted, the tillage depth of the farmland is changed and there is a secondary disadvantage in that the farmland cannot be evenly tilled.

본 발명에 따른 농업용 작업기는 도면에 도시된 바와 같이, 농용 트랙터의 후방에 동력 전달 가능하게 연결되어 장착된다.As shown in the drawings, the agricultural working machine according to the present invention is mounted to be connected to the rear of the agricultural tractor to enable transmission of power.
여기서, 농업용 작업기는 수확기, 로터베이터, 쟁기, 파종기, 베토기, 복토기, 트레일러, 베일러, 퇴비살포기 등이 있으나, 본 실시예에서는 농업용 작업기의 일례로 로터베이터(100)를 도면과 같이 예시하여 설명하기로 한다.Here, the agricultural work machine includes a harvester, a rotavator, a plow, a seeder, a mower, a soil cover machine, a trailer, a baler, a compost spreader, etc. Let's explain.
그리고, 로터베이터(100)가 장착되는 농용 작업 차량은 농용 트랙터를 일례로 들어 설명하기로 한다.And, the agricultural work vehicle to which the rotavator 100 is mounted will be described taking a farm tractor as an example.
한편, 상기와 같은 로터베이터(100)는 도 1 내지 도 6에 도시된 바와 같이, 트랙터 후방에 장착되는 탈부착부(200)에 연결되어 구비된다.On the other hand, as shown in Figs. 1 to 6, the rotavator 100 as described above is provided connected to the detachable part 200 mounted on the rear of the tractor.
이러한 로터베이터(100)는 도 1 내지 도 6에 도시된 바와 같이, 그 중앙부에 트랙터의 동력을 전달받아 구동되는 기어박스(110)가 일체로 구비되고, 이러한 기어박스(110)를 기준으로 로터베이터(100)는 좌우 양측이 균형을 이루게 된다.As shown in FIGS. 1 to 6, the rotavator 100 is integrally equipped with a gearbox 110 driven by receiving the power of the tractor at its center, and the rotor based on the gearbox 110. The batter 100 is balanced on both the left and right sides.
이와 같은 기어박스(110)의 양측 하부에는 도 6에 도시된 바와 같이 본축(main shaft)(111)이 기어박스(110)의 양측으로 돌출되게 구비되고, 본축(111)은 기어박스(110)에 의해 회전되면서 동력이 출력된다.As shown in FIG. 6, a main shaft 111 is provided to protrude from both sides of the gearbox 110 at the bottom of both sides of the gearbox 110, and the main shaft 111 is the gearbox 110 As it rotates, power is output.
그리고, 양 본축(111)의 외측 단부에는 거리 고정수단 즉 전산볼트(116)가 돌출되게 구비되고, 본축(111)의 내측 단부에는 제2 스프로킷휠(112)이 고정되게 구비되어, 제2 스프로킷휠(112)과 본축(111)이 동시에 회전되게 구비된다.In addition, a distance fixing means, that is, a computational bolt 116 is protruded from the outer ends of both main shafts 111, and a second sprocket wheel 112 is fixedly provided to the inner end of the main shaft 111, so that the second sprocket The wheel 112 and the main shaft 111 are provided to rotate simultaneously.
이로써, 트랙터의 동력이 동력전달부(120)를 통해 입력축(121)으로 입력되고, 입력된 동력은 제1 스프로킷휠(124)과 체인(125) 및 제2 스프로킷휠(112)을 통해 본축(111)으로 전달되어 출력된다.As a result, the power of the tractor is input to the input shaft 121 through the power transmission unit 120, and the input power is the main shaft ( 111) and output.
이러한 양 본축(111)에는 칼축(190)이 각각 상대 회전 불가한 상태로 결합되어 구비됨으로써, 양측의 칼축(190)이 본축(111)과 같이 회전되면서 농지를 경운하게 된다.The shear shafts 190 are coupled to both main shafts 111 in a non-rotatable state, respectively, so that the shear shafts 190 on both sides are rotated together with the main shaft 111 to plow farmland.
이때, 칼축(190)은 중공의 각관으로 형성되어 본축(111)의 외측에 끼워져 구비되되, 본축(111)은 그 외측면이 다각 형상으로 형성되고, 칼축(190)은 그 내측면이 본축(111)의 외측면에 대응한 다각 형상으로 형성되어 형상 맞춤되게 결합됨으로써, 본축(111)과 칼축(190)은 상대 회전이 불가한 구조로 결합된다.At this time, the shear shaft 190 is formed as a hollow square tube and is fitted to the outside of the main shaft 111, but the main shaft 111 has an outer surface formed in a polygonal shape, and the inner surface of the shear shaft 190 is the main shaft ( 111) is formed in a polygonal shape corresponding to the outer surface and coupled in a shape-fitting manner, the main shaft 111 and the knife shaft 190 are coupled in a structure in which relative rotation is impossible.
특히, 중공의 칼축(190)은 본축(111)에 결합된 상태에서 슬라이드 이동되어 본축(111)에서 돌출되는 양 칼축(190)의 폭을 조절할 수 있는 바, 이를 위해 중공의 칼축(190)에는 본축(111)에서 돌출되는 칼축(190)의 폭을 조절할 수 있는 폭조절 수단과, 폭조절 수단에 의해 조절된 칼축(190)을 고정시키는 고정수단이 구비된다.In particular, the hollow knife shaft 190 slides while being coupled to the main shaft 111 to adjust the width of both knife shafts 190 protruding from the main shaft 111. To this end, the hollow knife shaft 190 has A width adjusting means capable of adjusting the width of the cutting shaft 190 protruding from the main shaft 111 and a fixing means for fixing the cutting shaft 190 adjusted by the width adjusting means are provided.
이때, 폭조절 수단은 중공의 칼축(190) 내부에 구비되는 유압실린더(미도시)에 의한 자동화 구조로 구성될 수 있고, 또는 작업자에 의한 수동화 구조로 구성될 수도 있다.At this time, the width control means may be configured as an automated structure by a hydraulic cylinder (not shown) provided inside the hollow knife shaft 190, or may be configured as a manual structure by a worker.
게다가, 고정수단은 중공의 칼축(190)과 본축(111)을 관통하는 고정핀(미도시)으로 구성될 수 있고, 이러한 고정핀은 단독으로 구비되어 사용되어도 무방하지만, 후술될 전산볼트(116) 및 로크너트(117)와 함께 구비되어 사용되는 것이 하중에 의해 고정부에 작용되는 부하를 최소화할 수 있어 바람직하다.In addition, the fixing means may be composed of a hollow knife shaft 190 and a fixing pin (not shown) penetrating the main shaft 111, and such a fixing pin may be provided alone and used, but a computational bolt 116 to be described later ) and the lock nut 117, it is preferable to minimize the load applied to the fixing part by the load.
즉, 칼축(190)의 외측 단부에서는 전산볼트(116)에 로크너트(117)가 체결되고, 칼축(190)의 내측에서는 고정핀이 칼축(190)과 본축(111)을 관통한 상태로 체결됨으로써 칼축(190)을 본축(111)에 견고히 고정시켜 구비할 수 있게 된다.That is, at the outer end of the knife shaft 190, the lock nut 117 is fastened to the shear bolt 116, and on the inside of the knife shaft 190, the fixing pin is fastened while penetrating the knife shaft 190 and the main shaft 111 As a result, the knife shaft 190 can be firmly fixed to the main shaft 111 and provided.
또한, 상기와 같이 본축(111)에서 돌출되어 폭조절되게 구비되는 칼축(190)은 본축(111)과 40％ 이상 겹쳐진 상태로 구비됨이 바람직하고, 이 영역에서는 칼축(190)을 이용한 복토 또는 경운 등과 같은 로터리 작업시 칼축(190)과 본축(111) 사이에서 발생될 수 있는 유격을 없앨 수 있으므로 안정적으로 작업을 수행할 수 있게 된다.In addition, as described above, it is preferable that the cutting shaft 190 protruding from the main shaft 111 and provided to adjust the width is provided in a state of overlapping with the main shaft 111 by 40% or more. Since it is possible to eliminate the gap that may occur between the knife shaft 190 and the main shaft 111 during rotary work such as tillage, the work can be performed stably.
이러한 칼축(190)은 그 외측면 전체에 경운날(191)이 구비되어 경운 작업을 할 수 있고, 또는 칼축(190)의 외측 단부에 원형의 복토날(192)이 구비되어 복토 작업을 할 수도 있다.The shear shaft 190 may be provided with a tiller blade 191 on its entire outer surface to perform plowing work, or a circular soil cover blade 192 may be provided at the outer end of the shear shaft 190 to perform soil cover work. there is.
하지만, 경운 작업이나 복토 작업은 그에 맞는 날을 갖는 칼축이 장착된 로터베이터에 의해서만 이루어졌는데, 본 발명에서는 로터베이터(100)의 본축(111)에 경운날(191)이나 복토날(192)을 갖는 칼축(190)을 간편하게 교체하여 장착할 수 있도록 함으로써 하나의 로터베이터(100)로 여러 기능을 수행할 수 있게 된다.However, plowing work or soil covering work has been performed only by a rotavator equipped with a knife shaft having a corresponding blade. It is possible to perform several functions with one rotavator 100 by allowing the blade shaft 190 to be easily replaced and mounted.
즉, 본 발명에서는 로터베이터(100)의 본축(111)에 구비되는 칼축(190)을 트랙터의 성능 및 작업 목적에 따라 다른 규격의 칼축으로 교체할 수 있도록 구비된다.That is, in the present invention, the knife shaft 190 provided on the main shaft 111 of the rotavator 100 is provided so that it can be replaced with a knife shaft of a different standard according to the performance and work purpose of the tractor.
